Polyphosphoric acid (PPA) has a wide range of applications. my country has gradually become the world’s major producer and exporter.

Polyphosphoric acid (PPA), also known as tetrapolyphosphoric acid and polyphosphoric acid, is an inorganic substance with the chemical formula Hn+2PnO3n+1. It appears as a colorless, transparent and viscous liquid, and can be miscible with water and hydrolyzed into orthophosphoric acid. , does not crystallize. Polyphosphoric acid has the characteristics of good stability, strong water-based, low nucleophilicity, moderate acidity, strong oxidation, and high viscosity. It is widely used in the fields of medicine, pesticides, chemicals, food, electronics, spices, water treatment, etc. It is a first-class Chemical raw materials with high added value.

There are various production methods for polyphosphoric acid, mainly including high-temperature heating concentration method, electric energy method, absorption method, synthesis method, etc. Among them, the synthesis method is currently the mainstream method for industrial production of polyphosphoric acid. It refers to a method that uses phosphoric acid and phosphorus pentoxide as raw materials to generate polyphosphoric acid through heating, polymerization, purification, cooling, filtration and other links. It has low cost and process flow. It has the advantages of short length, simple operation and low pollution.

According to 《2023-2027 China Polyphosphoric Acid (PPA) Market Monitoring released by the Industrial Research Center And the research report on future development prospects》 shows that polyphosphoric acid has a wide range of applications. In the electronics field, it can be used in the production of lithium hexafluorophosphate electrolyte for power lithium batteries, and can also be used in integrated circuits, The cleaning agent and etchant production scenarios required for LCD panel production; in the chemical industry, it is mainly used in the synthesis of chemical products such as flame retardants, dehydrating agents, modified asphalt, metal surface treatment agents, catalysts; in the pesticide field, it can be used in phosphate fertilizer production scenarios. Currently, driven by the rapid development of downstream applications, the market demand for polyphosphoric acid is increasing. In 2022, the global polyphosphoric acid market demand will exceed 10 million tons.

Globally, the major companies in the polyphosphoric acid market include Israel’s ICL Phosphate Specialty, Japan’s Nippon Chemicon, Germany’s Lanxess, Switzerland’s Klein, France’s Arkema and other international companies, as well as Anhui Longhua Chemical, Jiangshan Yikang Chemical, Sichuan Ronghong Scientific and technological development, Kunming Fengdong New Technology, Jiangsu Chengxing Phosphate Chemical, Yunnan Phosphate Group, Guizhou Chuanheng Chemical, Harbin Boying Phosphate, Shangrao Ruisheng Chemical Materials, Anhui Sano Pharmaceutical and other Chinese companies.

In recent years, with foreign companies gradually withdrawing from the polyphosphoric acid market, the global polyphosphoric acid industry has continued to shift to China, and my country is gradually becoming the world’s major producer and exporter. In the future, leading local companies will need to continue to improve their technology and increase their supply capabilities of high-end polyphosphoric acid products, thereby accelerating their capture of the global market share.

Industry analysts said that polyphosphoric acid is a type of chemical raw material with high added value. In pesticides , medicine, chemical industry, electronics and other fields are widely used. With the rapid development of the downstream market, global demand for polyphosphoric acid continues to increase, and the industry has broad prospects for development. In recent years, the global polyphosphoric acid industry has been continuously shifting towards China. my country has gradually become the world’s major producer and exporter, and the overall development trend of the polyphosphoric acid industry is improving.
